With the growth of big data, cloud and high performance computing, demands on data centers around the world are expanding every year. Unfortunately, these demands are coming up against significant opposition in the form of operating constraints, capital constraints, and sustainability goals. In this article, we look at 8 of these constraints and how direct-to-chip liquid cooling is solving them.
PNNL researchers are using supercomputers to take on two of the main challenges of exascale: energy efficiency and resiliency. Their simulations show that dynamic voltage scaling, also known as undervolting, can reduce power consumption and leverage existing mainstream resilience techniques at scale for improving system failure rates.
“This talk will discuss various strategies to make a serial Python code faster, for example using libraries like NumPy, or tools like Cython which compile Python code. The talk will also discuss the available tools for running Python in parallel, focusing on the mpi4py module which implements MPI (Message Passing Interface) in Python.”
Today Sandia National Laboratories announced that researcher Mark Taylor has received the U.S. Department of Energy (DOE) 2014 Secretary’s Honor Award — the department’s highest non-monetary employee recognition — for his work as chief computational scientist for DOE’s Accelerated Climate Modeling for Energy (ACME) executive council team.
The Partnership for Advanced Computing in Europe in Europe has published the first edition of PRACE Women in HPC Magazine, a collection of success stories celebrating the contribution women make to HPC and computational science. Designed to put the spotlight on the scientific advances made in the past year, the magazine tells the story of women who help make PRACE a world-leading force in HPC-enabled science and the march towards Exascale computing.
